SHACKLE.

Application led March 22, 1,923. Serial No. 626,875.

Be it known that I, HUGH C. LORD,`a citizen of the United States, residing at Erie, inthe county of Erie and State ofPennsylvania, have invented new and useful Im-` provements in Shackles, of which' the following is a speciiication.

This invention is particularly designed to "improve shackle hangers. Such hangers are commonly used with shackles for springs. It is particularly suited for a joint made up ofsections in which there are swinging parts to which the hangers are attached. In carrying out my invention I preferably use la strap of metal, bend eyes in the strap of metal, and form return extensions which may be utilized for closing the eyes on the joint parts. Other features of the invention will appear from the specification and claims. The invention is illustrated in the accompanying drawings as follows Fig. 1 shows a rear end of an automobile with a spring hanger in place.

Fig. 2 a central vertical section through the shackle and joints. A 1

Fig. 3 a sie@ elevation or the shackle in,

' serted in the sleeve 2 and another in the spring eye with a pressed it. The rubber joint elements 8 are secured to the outer ends of the pin and these are enclosed' by metal shells 9.y The hangers are secured to these outer shells 9.

The hanger is formed of a'bar 10 in which is bentthe eye 11 with a return extension 12 and an eye 13 with a return extension 14. These extensions and the connecting bar have the openings 15 through which a clamping bolt 16 is passed. The clamping bolt is provided with a nut 17 and a lock washer 18. The opening 15 is preferably square and what is commonly known as a carriage bolt is used so as to lock it in the squared opening. I prefer to make the extensions 12 and 14 slightly bent so that they are put under initialtension and the ends .bar and closing t e eyes by crowded into closer engagement with the connecting bar. This tends also to facilitate the closing of the eyes 11 and 13 so as to .clamp these eyes on the shells 9. In order to brace the two hangers, one at each side of the joint, it is `preferable to have a cross bar and this is provided in this structure by a brace extension 19. which is formed by extendingthe bar from the eye 13 with a brace eye 20 in its lower end and the bar turned upon itself so as to continue the eye 13. The two parts 19 are connected by spot welding at 19a. A cross pin 21 has the reduced ends 22 which extend through vthe eyes 2() and nuts 24 are arranged at the outer ends clamping these in place, the reduced portion forming a shoulder 23 which opposes the nut 24.

Closure caps 25 are arranged. over the eyes 11 and 13. These are secured -to the edges of these eyes by spot welding at 26. They vare secured only at one side of the eye and preferably the side opposite' the extensions 12 and 14 so as not to interfere with `the clamping movement of the eyes.

What I claim as new is 1. A shackle hanger comprising a connecting bar; clamping eyes formed on the connecting bar; return extensions on the eyes projecting along the bar; and means clamping the extensions on the bar and closing the eyes by the springing of the metal ofing bar; clamping eyes formed on the conreturn extensions on the eyes projecting alon the bar; and means clamping the extensions on the bar and closing the eyes by the springing of the metal of the eyes, said extensions being initially bent whereby they are under tension when in place.

4. A shackle hanger comprising a connecting bar; `clamping eyes formed on the connecting bar; overlapping return extensions on the eyes projecting along the bar; andmeans clam ing the extensions on the thesprmging of necting bar;

vao

necting bar; clamping eyes formed in the connecting bar, sald eyes extending from op? posite sides of the bar; return extensions on the eyes projecting along the bar; and means clam ing the extensions on the bar for closing t e eyes.

A shackle hanger comprising a connecting bar; clamping eyes formed on the connecting bar; return extensions on the eyes projecting along the bar; and means clampmg the extensions on the bar and closing t e eyes by the springing of the metal of the eyes, said hanger having a brace eye formed in the bar.

8. Ay shackle hanger comprising a connecting bar; clamping eyes formed on the connecting bar; return extensions on the eyes projecting along the bar; and means clamp- 1ng the extensions on Ithe bar and closing the eyes'by the sprin 'ng of the metal 'of the eyes, said hanger aving a brace extension om one eye and a brace eye formed in the extension.

9. In a shackle, the combination with a joint member; shackle hangers arranged at each end of said joint member, said hangers comprising connecting bars; clamping eyes formed on the connecting bars; return extensions on the eyes projecting along the bars; and means clamping the extensions on the bar and closing the eyes on the' joint member.

10. In a shackle, the combination with a jolnt member; shackle hangers arranged at each end of said joint member, said hangers comprising connecting bars; clamping eyes formed on the connecting bars; return extensions on' the eyes projecting along the bars; means clam'b ing the extensions on the bar and closing t e eyes on the joint member;abrace eye formed in the bars; and a connecting brace between the eyes.

Temeon 11. In a shackle, the combination with a joint member; shackle hangers arranged at each end of said joint member, said lmngers comprising connecting bars; clamping eyes formed on the connecting bars; return extensions ony the eyes projecting along the bars; means clam ing the extensions on the bar and closing t e eyesl on the joint member; a brace extension extending from the two opposite eyes; a' brace eye formed in the brace vextension; and a. bar extending throu h the brace eyes.

12. n a shackle, the combination with a joint member; shackle hangers arranged at each end of said joint member, said hangers comprising connecting bars; clamping eyes formed on the connecting bars; return extensions on the eyes projecting alongthe bars; means clamping the extensions on the bar and closingthe eyes on the joint member; a brace extension extending from the two opposite eyes; a brace eye formed in the brace extension; and a bar extending through the brace eyes, said bar having reduced ends and clamping n uts :at its ends.

13. A-shackle joint hanger having clamp-V ing eyes at its ends and cover plates arranged over said eyes.

14. A shackle joint hanger having clamping eyes at its ends and cover plates arranged over said eyes, said cover plates be-A ing secured at vone side of said eyes.

-15.A shackle hanger com rising aconnccting bar; clamping eyes ormed on t-he connecting bar; return extensions on the eyes projecting along the bar; means clamping the extensions on the bar and closing the eyes by the springing of the metal of the eyes; and cover plates secured to the edges of said eyes and covering said eyes.

16. A shackle hanger comprising a connecting bar; clamping eyes formed on the connecting bar; return extensions on the eyes projecting along the bar; `means clamping the' exten'slons on the bar and closing the eyes by the springing of the metal of the eyes and cover plates secured to the edges of said eyes closing one end of said eyes, said cover plates being secured at one side of the eyes to permit of the closing of the eyes.

In testimony whereof I have hereunto set my hand. p
